Question

The area of a triangle is equal to that of a square whose each side measures 70m. Find the base of the triangle when the hight is 98m​

Answer 1

Answer:

let base of triangle = x

x * 98/2 = 70 * 70

x = 70 * 70 * 2/ 98

x = 100m

Answer 2

Given:-

Area of triangle = Area of a square.

Side of a square = 70m.

Height of the triangle = 98m.

To find:-

The base of the triangle.

Solution:-

Area of square = (side)²

= (70)²

= 4900 m²..

Area of triangle = Area of square = 4900m²

Now,

Area of triangle = 1/2 × b × h

=> 4900 = 1/2 × b × 98

=> 4900 = 49b

=> 4900/49 = b

=> b = 100 m..... (ans)
